I'm seeing slow perf as well but I think it might be a jruby/292 mismatch
problem:
Exception <a 'java/lang/NoSuchMethodError'>:
java.lang.invoke.MethodHandles.convertArguments(Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodT\
ype;)Ljava/lang/invoke/MethodHandle; (0xefdd4b18 )

line 354]
for thread 0x0807c800

Exception <a 'java/lang/NoSuchMethodError'> (0xefdd4b18 )
which results in this:

So I think the jruby compiler never triggers with the new meth.jar.
